Rupture Spire

Great land for Rainbow decks good for getting color you need to play cards a land that definitely makes its mark as a good multicolor land and helped revolutionize rainbow decks more gotta love Alara, Conflux, and Alara Reborn.

no really it IS a birds of paradise think about it; it costs one to play, it comes into play tapped like summoning sickness; and you can tap it for one of any color. personally i think it's better because it doesn't cost eighth bucks

i love this card just the fact that it doesnt eat away at your other mana sources and its land so thats always good

An all-color mana producing common that doesn't continuously eat mana from other sources? Sure it plays slow and is no birds of paradise, but it is nothing to bat an eye at either.

Actually, it cost two to play: It comes into play tapped, and you have to pay one mana to keep from sacing it. It's too slow. There's a reason these seemingly great dual lands are common and/or dirt cheap. They slow down your deck too much. That being said, in a loose casual setting where you're not facing an uberexpensive deck, they are a cheap alternative to the more expensive fetchlands or dual lands.
